Description Nico Gulden

A user reports that UCS updates destroy the bootloader settings.

An upgrade from UCS 4.2-3 to UCS 4.3-1, as well as, package updates on UCS 4.3-1 destroyed the boot loader configuration. Both systems did not boot anymore and resulted in a blinking prompt.

The partitioning is quite simple:

* Swap (dev/sda1)
* / (dev/sda2)
* Additional hard disk (/dev/sdb) for data, mounted at /media/data
 
The boot loader is installed in the MBR on /dev/sda.

The user restored the boot loader with Super Grub2 CD and the instructions from https://help.univention.com/t/boot-ucs-system-via-super-grub2-disk/6409

The user executed the updates with apt-get upgrade (for package update) and apt-get dist-upgrade for the upgrade to the next UCS version.
